Hormuz remains physically open, but normal traffic is still far away
Commercial transits through the strait are confirmed, but flows remain far below normal and security/access conditions are severe. It is not physically closed; it is operating on a highly constrained basis.

Commercial transits through the strait are confirmed, but flows remain far below normal and security/access conditions are severe. It is not physically closed; it is operating on a highly constrained basis. Today's edition separates what is happening on the water from political statements and market reaction.

- Whether commercial crossings recover for several consecutive days or fall again towards a near-total pause.
- New JMIC/UKMTO advisories, confirmed attacks, interference or changes in escorts and naval presence.
- Changes in imposed routes, inspections, permissions, sanctions, insurance or selective passage conditions.
